Fits Keter sheds!
This is perfect to use on Keter sheds (like the newer Darwin model) with the small lock holes. Even small padlocks struggle to fit the lock space, but with this device you can use any lock you desire!

Got these for added layer of security
I got this as a added layer of security for bike cover on motorhome just enough space for the four steel eyelets to be locked together making it harder to remove cover with out cutting off, anything to help slow them down

Just right for multiple padlocks for one box
Never used one of these before, but was after something for an escape room puzzle box where I can lock a box using more than one padlock. This is just the thing for it - seems robust and the size of the holes seems spot on for standard padlocks.

Produit conforme à sa description, ni plus ni moins. Les trous sont assez gros pour pouvoir y mettre tous les cadenas que l'on souhaite

He hecho un break out con eso y me ha ido perfecto para poner todos los candados necesarios.

These have one purpose and as they have one purpose they have only do one thing and that is to lock out potential electrical energy from being released by the system being locked out. This they do very well and they are durable. The key with this product is it only works if all parties work together and do their part. The device itself is worthy and it does its part. You can count on it to do what it was designed. Getting all who use it to do their part is another issue altogether.

Ist für meinen Zweck gut geeignet. Ich habe einen Schrank, der mit einem Vorhängeschloss verschlossen werden sollte; die einigermaßen stabilen Schlösser hatten jedoch eine zu großen Bügel und es war immer eine Riesen Fummelei, das Vorhängeschloss einzufädeln. Mit dem Masterlock ist es sehr einfach und für mein Empfinden genauso sicher wie nur mit Vorhängeschloss.

Worked perfect for the game we created, while they had to find the right keys for multiple locks.
